It is based on the Richard Speck's case of the year before.
Serie noire (1979) Uneven, as it alternates comedy and drama and so even the characters do not appear to be well defined and credible. Blier's especially is absurd in the finale and so the wife's, her insisting where D. got the money (and how does she come to infer that the money is related to the double murder, as all the papers concur in describing the old woman as pennyless?). The part with D. and the Greek at D.'s home doesn't make sense and could have been cut out profitably. D. thinking that B. won't check on him and wonder where he got the money is incredible. I'll check the Thompson book (with little hope it will make more sense than the movie). 6/10
The Boston Strangler (1968) Excellent thriller, making excellent use of multipanel screen. What doesn't persuade me completely is the cast. Yeah. Fonda is wasted: the role is too small for him. Curtis has been praised for it, still, I'm not 100% sure he's here as good as in Sweet Smell of Success. His closing his eyes when murdering is too banal. Still the movie grips you from start to end. 9\10
The Battle of Algiers (1966) I saw this twice before and never particularly impressed if not by the great final scenes. But even the thriller main body of the story, on a bigger screen, acquires value on a bigger screen with the Casbah labyrinth being a great set. There are some melodramatic scenes which do not belong to any of the two parts of the story, which are made even worse by Morricone's (or Pontecorvo?s) comment. So I give it 7-8/10.
this is better than 8/10
